Answer:
x=5, y=-10
Step-by-step explanation:
y = x²-10x+15 --- eqn 1
y = -10 --- eqn 2
Sub eqn 2 into eqn 1:
x²-10x+15 = -10
x²-10x+15+10 = 0
x²-10x+25 = 0
(x-5)² = 0
x-5 = 0
x = 5
Answer:So the answer is 540 degrees
Step-by-step explanation:
The best way to do this is by using the equasion of 180*(n-2) so what you would so is 180*(5-2) or 180*3= 540
(3.5 × 100) × 1100 = 350100.
Write in percentage notation: 350%
Answer:

Step-by-step explanation:
Use inverse operations and simplification to isolate the variable in the equation.

Now divide the equation by
remember, dividing a fraction is the same as multiplying by the reciprocal. The reciprocal of a fraction is when one switches the places of the numerator (number on top of a fraction bar), and the denominator (number on the bottom of the fraction bar).
